# La Cornue diagnostic visit cost

### What the fee actually buys on this equipment

A number instead of an opinion. The gas half of a La Cornue reports nothing at all — no display, no code, no history — so the only alternative to measurement is replacing parts in order of likelihood, which on an appliance whose components sometimes come from France is an expensive way to think. The visit ends with what was measured, what it means, what the part costs, what the lead time is and what we recommend, in writing. If the finding is that nothing is wrong, that is what the report says.

What moves this figure

from $95, credited toward the repair

A measurement, not an opinion — there is no code to read on most of this line

Scope and figure in writing before anything is opened

Which model and which configuration

A Château 150 in a K3 top and the same range in a K6 need different parts for the same complaint. Reading the configuration is part of the visit.

Whether there is anything to read at all

Only the induction and all-electric models can show a code. On a gas Château there is nothing to read and the diagnosis is entirely instrumented.

How many appliances are involved

A range, its hood and sometimes a Tourelle in one kitchen. Looking at a second appliance on the same visit costs a fraction of a second visit.

Whether it turns out to be nothing

It sometimes does — an H on the display, a pan below the minimum diameter, a vaulted oven behaving as designed. The fee is what lets us say so instead of finding something.

What the access costs

Almost always nothing here: these ranges are served from the front where they stand. Only one job on this site prices moving one.

### Is the fee credited if I go ahead with the repair?

Yes. It comes off the repair on the same visit, which is the fleet's rule and not a concession. What it is not is a free estimate: a diagnostic on this equipment involves gas pressure readings, current measurements on igniters, calibrated shelf temperatures and a written report, and that work has a value whether or not you choose to proceed.

### Can you quote over the phone instead?

For a lamp or a set of baffle filters, sometimes. For anything else, no — and on this make the reason is specific. Two ranges with the same model number can have different modules under the lids, so a phone quote would be a guess dressed as a figure. What we can do on the phone is tell you which of the pages on this site your symptom matches and what the likely range is.
